Prof. Luca Parra (CCNY Biomedical Engineering), On Brainwaves and Videos and Video Games

Thursday, February 09, 2017, 03:30 PM, NAC 4/156

What are the immediate neural response of the brain to natural stimuli, in particular audiovisual narratives and video games? To answer this question we record EEG while subjects are exposed to the identical audiovisual narratives and measure inter-subject correlation, which captures how similarly and reliably different people respond to the same natural stimulus. We find that inter-subject correlation of EEG is strongly modulated by attention, correlates with long term memory, and provides a quantitative estimate for “audience engagement”. In children and adolescents watching videos we find changes with age and gender that are consistent with an increase in diversity of brain responses as they mature. During video game play, which are unique experiences that preclude correlation across subjects, we measure the strength of stimulus-response correlations instead. We found that correlation with both auditory and visual responses drive the correlation observed between subjects for video and that they are are modulated by attention in video game play. Importantly, the strongest response to visual and auditory features had nearly identical neural origin suggesting that the dominant response of the brain to natural stimuli is supramodal.

The “Non-invasive neuromodulation technology and regulation meeting” is a national meeting covering topics on the commercialization and regulation of non-invasive neuromodulation technology intended for medical and wellness use. This intensive one-day event is in direct response to the proliferation of clinical trials, popular press coverage, and now consumer-directed devices. The meeting is focused on transcranial Direct Current Stimulation (tDCS) but spans any investigational techniques or marketed technologies that apply electrical energy to the head. Ample time will be allowed for discussion with speakers.

Date: August 28, 2016
Location Center for Discovery and Innovation (CDI) Room Number – 4352

Dr. J. Patrick Reilly, among the pioneers in electrical stimulation theory, will provide an detailed overview on theory and application. Topic covered include cellular modeling of electrical stimulation, waveform effects, electrical sensations and pain, Among many papers and books, Dr. Reilly is the author or Applied Bioelectricty and he may have a broader perspective on the development of electrical stimulation theory than anyone in the world. Dr. Reilly will provide a series of lecture from  9:30 AM to 2:45 PM (with lunch break) at the CDI.
